我对 WPF 很陌生，似乎无法正确显示我的表单。我预计会有 6 行。前三个应该有按钮，最后三个包含更多的网格。我正在关注 NHibernate 电子书中的代码，但它似乎无法正确显示。有人可以看看这段代码并提出任何可能的错误：

最后一个网格与第 5 行的网格重叠，这些行：

<av:Grid x:Name = "ProductGrid" Margin="-1,2,1,130" av:Grid.Row="5">
<av:Grid x:Name = "LoadCategoryGrid" av:Grid.Row="5" Margin="3,73,-3,128" >

将两个网格放在同一网格行，查看av:Grid.Row具有相同值的附加属性。要将其中一个移动到空闲位置，必须更改为：av:Grid.Row="4"

除了杂散的双重定义Grid.Row="5"和Grid.RowSpan="2"只定义了一行，你现在已经修复了这两个，唯一会影响定位的其他代码是所有的虚假Margin值。

除此之外，XAML 看起来还不错。
